This example demonstrates using a pattern for filling the area in an area chart, together with a number of chart formatting features.<br><br>
<ul><li> Create an XYChart object with background color and border using <a href="XYChart.XYChart.htm">XYChart.XYChart</a>.<br><br>
<li> Set the background color of the title box using <a href="Box.setBackground.htm">Box.setBackground</a>. The background color is a pattern color created using <a href="BaseChart.patternColor.htm">BaseChart.patternColor</a>.<br><br>
<li> Enable both vertical and horizontal grid lines using <a href="XYChart.setPlotArea.htm">XYChart.setPlotArea</a>. The grid colors are dash line colors created using <a href="BaseChart.dashLineColor.htm">BaseChart.dashLineColor</a>.<br><br>
<li> Create a pattern color with a "snow pattern" loaded from an image file using <a href="BaseChart.patternColor2.htm">BaseChart.patternColor2</a>.<br><br>
<li> Use <a href="DataSet.setDataColor.htm">DataSet.setDataColor</a> to specify the area fill and border colors. Use the "snow pattern" as the area fill color.<br><br>
<li> Use <a href="Layer.setLineWidth.htm">Layer.setLineWidth</a> to increase the border width of the area to highlight it.</ul>
